Smile New engine!

hi guys

me again.

iv had running issues for some times now, and it turned out to be a rather large lack of compressoin on cylinder 2.

the problem has now been resolved with a new engine, wel la replacment one anyway.

can feel all the power back but now its back to tuning and its not runnning right.

my idle is a bit strange as its a little high and the idle screw is screwed all the way in.

the idle is around 1300 to 1500 but it keeps triggering the accel enrichment causing it to run rich for just second which makes the idle drop, so its going up and down sounding like a bit of a misfire because of the richness.

i am also getting very violent kangarooing through the rev range and VE live isnt doing anything.
im guessing its a fueling thing but thought id see what people think.

i reset my timing as that was out which wasnt halping and i was woundering weather i should recalubrate the inovate wideband?

if you wouldnt mind taking the time to respone with advice i would be very greatful.

heres the msq if it helps

Have you checked for vacuum leaks?

Back out the idle set screw until your RPMs drop.

Likely running lean. Burn a log file and post it here.

A cold air calibration on a Innovate is always a good idea.

Im just telling you that too much timing and nothing will lower your idle. Or air leak.

right i managed to get out and start from scratch with a brand new map.
now the idle is spot on, i just cant seem to tune out the next issue which is the violent kangarooing at low revs or holding of revs.
What seems to be happening is the accel enrichment light flashes on and then the deccel enrichment light flashes on. im not sure how to stop this from happerning.
I also have no idea how to turn off the AE as some recomeded turning it off and the tune the fuel map then turn it back on again?

either way im little confused.

i was also woundered weather turning the overrun fuel cut back on and lowering the KPA dowwn to either 30 -20?

any ideas?
